The present invention relates to anchors and is articularly concernedwiththe provision of anchors for attachment to logs or other membersusually termed dead men.

One of the objects of the present invention is the provision. of a deadman anchor which 1s quickly attached to logs'or other members which maybe buried in the earth later desired to abandon the anchor.

and which permits thedriving of a guy rod attachedthereto into the earthwhen it is Another object of the invention is the provision of a deadman anchor including means for the distribution of the strain over anextended surface of the dead man and quick detachable'means forconnecting a guy rod to said first mentioned means.

Another object of the invention is the provision of a dead man anchorcomprising a strain distributing plate and a detachable L thrust collarwhich are easily removed and of a guy rod to the dead man assembled andwhich permit the attachment anchor without the necessity-of specialtools. Y i r r Another object of the invention is the provision ofsimple andefiective means for securing an. ordinary guy rod having anenlarged end which maybe pointed or merely vention will appear, morefully from the folupset toa dead man through which the guy rod passes. v

Other objects and advantages. of myinlowing description and-from theaccompanylng drawings inwhlch simllarcharacters of reference lndlcate smilar parts throughout I the several views.

,. Referring to thesingle sheet of drawings:

Referring to Figure 1, IOindicates in its entirety, a log, timber, metalbody or other 'realtively fixed member which is usually perspectiveofthe en- 1928. s rial No. 268,693.

termed a dead man. The dead man is usually buried in the earth andpresents a relatively large surface for engaging the earth above itandincreasing the holding power of any member which may be secured 5thereto.

I desire it to be understood, however, that m invention may be used forattaching guy rods .to other members besides those buried in the earth,such as trees, poles, and the like, whenever such procedure may bedesirable. Consequently, the term dead man is employed throughout'thisspecification and in the claims in the generic senseof including anyrelatively'fixed member to which it may be desirable toattach a guy rod.

The dead man 10 is attached to the guy rod 11 by means of a securingdevice indicated in its entirety at 12. The securing device 12 comprisesa metal plate 13 of suflicient thickness andarea to distribute thestrain transmitted to it by the guy rod over a considerable'portion ofthe dead man 10.

The plate 13 may be of any shape but is preferably provided with acentral aperture 14 of sufi'icient size to pass'the head 15 of the guyrod 11. The aperture 14 is also formed with a pair of grooves 16 adaptedto pass lugs 17 carried by a sectional thrust collar which isindicatedin itsentirety at 18 in Figure 4. 30 Theplate 18 is'alsoprovided with apertures 19 adapted to receive screws or other fasteningmeans for securing the plate on the dead man 10. The sectional thrustcollar 18 may consist of a plurality of sections adapted to be assembledtogether to form a collar embracing the guy rod 11 and filling theaperture 14 of the plate. In the present instance, two semi-cylindricalsections 20 and 20 are provided, each having an axial groove 21'ofsufficient size so that when the two sections are assembled an axialbore 22 is formed which embraces "the guy rod 11. The semicylindricalsections20 and 20 are each provided with a flange 23 extending atsubstantially right angles and adapted to engage the plate 13 to limitthe movement of the thrust collar relative to said plate, and the outersurface of the flange 23 is preferably formed as shown in Figure 3 witha grooved surface 24 complementary to the inner edge of the head uponthe guy rod 11. For convenience in casting, the grooves 21 in the thrustcollar sections and 2O? may be larger than necessary to receive the guyrod 11, but may be provided with hearing portions 25 and 26 at each endof substantially semi-cylindrical form and adapted to fit about the guyrod 11.

Carried by the trust collar sections 20 and 20 are a pair of lugs 17having their lower edges 27 sufficiently spaced from the flange 23 toreceive the plate 13 between the lu s 17 and the flange 23. The lugs 17may be of any be passed through the bore 14 of the plate 13,- when thelugs 17 register with the grooves 16,

after which the thrust collar may be rotated relative to said plate, thelugs 17 passing out of registry with the grooves 16 and engaging belowthe plate 13 to engage the collartherein;

' The assembly and operation of my anchordevice with the dead man is asfollows: The dead man is providedwith a bore 28, preferably ofthe samesize as the aperture 14 in the "plate 13. The guy rod 11 may then haveits head 15 inserted through the bore 28 and the aperture 1 1 and thethrust collar 18' may be assembled upon 'the guy rod between the head.15 and the plate 13, after which the thrust collar may be passed throughthe apertures 14 and rotated, as previously described, to retain thecollar in assembled relation with the plate and dead man. The assembledstructure of the thrust collar and plate may then be forced into thebore 28, the lugs 17 forming grooves in the bore in which they will bereceived to prevent the thrust collar from rotating. The plate maythen-be secured to the dead manby screws passing through the holes inthe plate and the plate should preferably be secured so that the grooves16 do notregister with the lugs 17. The plate being secured againstrotation by its screws, and the thrust collar being secured byfrictional engagement of its lugs in the bore, these parts will then beheld 1 against relative rotation and the thrust collar cannot bedetached from the plate without first removing the plate from the deadman.

The foregoing structure is easily manufactured and assembled and thethrust collar 18 provides a means for transmitting the thrust from thehead of the guy rod to the plate 13 which distributes the strain over asubstantial area of the dead man."

While I have illustrated anddescribed a specific embodiment of myinvention, many modifications may be made without departing from thespirit of the invention, and I do not 'wish to-be limited to the precisedetails of bore through the same with a strain distributing platecarried at one side of said member and having an aperture aligned withsaid bore, a guy rod having an enlargedhead adapted to pass said boreand aperture, and sectionalmeans adapted to be received by said bore forpreventing withdrawal of said head. 7
